(Specification)Standard Specification for Structural Standing Seam Steel Roof Panel Systems
Standard Specification for Structural Standing Seam Steel Roof Panel Systems
ABSTRACT
This specification covers the design, construction, and weatherability of structural standing seam steel roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers. Panel material shall be a hot dip metallic coated product in accordance with one of the following commonly used materials: aluminum-, aluminum-zinc alloy-, zinc-, or zinc-5% aluminum alloy metallic-coated sheet steel. The roof system shall be designed for specified design loads and thermal effects without causing seam separation, permanent panel buckling, or weather-tightness loss. Deflection and serviceability shall be accounted for in the panel system for structural integrity. Static and uplift index tests shall be performed to determine the roof's load capacity. Standing seam roof panel systems shall be installed in accordance with the system design requirements.
SCOPE
1.1 This specification covers the design, construction, and weatherability of structural standing seam steel roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers.
Note 1: These systems are used on both low-slope and steep-slope roof applications. They also are used with or without an underlying deck or sheathing.
1.2 The objective of this specification is to provide for the overall performance of the structural standing seam steel roof panel system as defined in 3.2.6 during its service life in order to provide weather protection, carry the specified design loads, and allow proper access over the roof surface in order to provide for periodic maintenance of equipment by the owner.
1.3 In addition to structural, the specifier shall evaluate other characteristics beyond the scope of this specification that affect the final choice of roof construction. These include, but are not limited to, functional, legal, insurance, and economic considerations. See Appendix X1 for specifier's checklist.
1.4 The specification is not intended to exclude products or systems not covered by the referenced documents.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 The text of this specification contains notes and footnotes that provide explanatory information and are not requirements of this specification.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.3 Oil Canning—Oil canning is an inherent characteristic of products covered by this specification, particularly those with
broad, flat areas. It is the result of several factors that include, but are not limited to, induced stresses in the base material,
fabrication methods, and installation and thermal forces. While oil canning is an aesthetic issue, structural integrity is not normally
affected. Oil canning is not grounds for panel rejection, unless it does not meet prior standards established by the specifier.
5. Structural Integrity
5.1 Panel System Design:
5.1.1 Structural panels shall be designed in accordance with AISI Specification for the Design of Cold-Formed Steel Structural
Members—and in accordance with sound engineering methods and practices.
5.1.2 Deflection and serviceability shall be accounted for. The deflection shall be limited so as to allow the roof to perform as
designed. The substrate deflection shall not cause strains to the panels that affect the serviceability of the system.
5.2 Panel System Testing:
5.2.1 Static (Positive or Negative Load Capacity)—When the panel system does not comply with the requirements for using the
design procedures of the AISI Specification, testing shall be performed to determine the roof’s load capacity.
5.2.2 Uplift Index—When required by the specifier, the roof system shall be tested in accordance with the requirements of 5.3
of FM Approvals Approval Standard 4471, orUnderwriters or Underwriters Laboratories UL 580, or Test Method E1592 or other
applicable tests (see Appendix X2).
6. Panel Material
6.1 Panel material shall be a hot dip metallic coated product in accordance with one of the commonly used materials listed in
6.1.1 – 6.1.4.
6.1.1 Aluminum coated sheet steel produced to the requirements of Specification A463/A463M. Coating designation T265.
6.1.2 Aluminum-zinc alloy coated sheet steel produced to the requirements of Specification A792/A792M. Coating designation
AZ-55. When an organic finish coating is used (as described in 6.2), coating designation of AZ-50 shall be permitted.
6.1.3 Zinc coated sheet steel produced to the requirements of Specification A653/A653M. Coating designation G90.
6.1.4 Zinc-5 % aluminum alloy metallic-coated sheet steel produced to the requirements of Specification A875/A875M. Coating
designation GF90.
6.2 In addition to the foregoing material specifications, the specifier has the option to require organic finish coatings.
6.3 This specification does not preclude the use of other coating standards governing the same materials, as long as equivalency
is established. The designer shall determine the suitability of material for the application.
6.4 Steel grade and base metal thickness shall be as required to resist specified design loads.
7. Panel Clips
7.1 Connections of panels to structural members shall be made with concealed panel clips compatible with the panel design.
7.2 Provisions for the thermal movement between the panel and the structure to which it is attached shall be accomplished by
the use of concealed panel clips allowing such movement, except as provided in 7.3.
7.3 When the building geometry and the rotational flexibility of the supporting member permit, it is permissible to resolve
thermal movement through controlled rotation of the intermediate structural members rather than movement within the clip.
7.4 Where insulation is applied between the panels and supporting structure, the panel clips shall be designed to be compatible
with the thickness and compressibility of the insulation. If thermal spacers are required for thermal performance, the clips must
be compatible with the thermal spacer to reduce secondary stresses due to walking.
8. Panel and Clip Anchorage
8.1 A fixing line is required to anchor roof panels in order to maintain end alignment and to resist in-plane gravity and thermal
force components.
8.2 Fasteners that penetrate the roof surface are permitted only at panel endlaps, penetrations, fixing lines, rib reinforcements,
and at roof termination lines. Details at these locations shall allow for the expected thermal movement.
8.3 Nails shall not be used where subject to withdrawal loads.
9. Weather Tightness
9.1 Panel-to-panel sidelap connections and endlaps shall be weathertight.
9.2 Panels of maximum practical lengths shall be used to minimize endlaps.
Fisher, James M., and West, Michael A. “Serviceability Design Considerations for Low Rise Buildings,” AISC Design Guide No. 3.
Equivalency shall be evaluated on the basis of minimum coating (thickness) of same material, according to the appropriate ASTM Specification.

E1514 − 98 (2017)
9.3 Sealers:
9.3.1 Sidelap Sealer—When climate, roof slope, and roof system design warrant, the standing seam sidelap shall have a sealer.
When the sealer is factory applied, it shall remain in place and be protected during transit. In some cases, the panel geometry will
provide the required protection. All sealers shall remain in place during panel installation and be protected during storage and
installation from any contamination or abrasion that unduly affects service.
NOTE 3—When the slope of the roof is steep, or when the roof system is in a geographic area with little rainfall or snowfall, a sidelap or endlap sealer
may not necessarily be required.
9.3.1.1 The sealer shall be of sufficient size and shape to fill the maximum void to be sealed and to assure compression after
engagement. The minimum compression shall be 30 % by volume or the adhesion plus webbing characteristics shall be as required
to maintain watertightness. An appropriate test shall be used to demonstrate the roof panel system’s resistance to ponded water.
The sealer shall remain flexible between 0 and 140°F140 °F (−17.8 and 60°C)60 °C) to allow engagement, and shall show no signs
of cracking when tested in accordance with Test Method C765 (wrapped 180° over a 1 in. (2.54 cm) diameter mandrel after 4 h
at −0°F (−17.8°C)).−0 °F (−17.8 °C)). The sealer shall not be exposed
